How to transform each side of a shape separately? - html

How do I create a CSS shape in which each side is transformed separately.
Something like the shape in the below image.
Is that possible using CSS only without images?

I don't think there is any way in CSS to pick and transform each side separately but you can achieve the shape in question by using perspective transforms (pure CSS).
Rotating the element with perspective along both X and Y axes sort of produces the effect of each side having a separate transformation. You can adjust the angles and the perspective setting to create the shape exactly as required.
.shape {
background: black;
margin: 100px;
height: 200px;
width: 200px;
transform: perspective(20px) rotateX(-2deg) rotateY(-1deg); /* make perspective roughly 10% of height and width */
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<div class="shape"></div>
Or, you could make use of the clip-path feature. Clip paths can be created either by using CSS alone or by using inline SVG. SVG clip paths have much better browser support than the CSS version.
div {
height: 200px;
width: 200px;
background: black;
}
.css-clip {
-webkit-clip-path: polygon(0% 10%, 100% 0%, 85% 100%, 15% 95%);
clip-path: polygon(0% 10%, 100% 0%, 85% 100%, 15% 95%);
}
.svg-clip {
-webkit-clip-path: url(#clipper);
clip-path: url(#clipper);
}
/* Just for demo */
div{
display: inline-block;
margin: 10px;
line-height: 200px;
text-align: center;
color: beige;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<!-- CSS Clip path -->
<div class='css-clip'>CSS Clip Path</div>
<!-- SVG Clip path -->
<svg width='0' height='0'>
<defs>
<clipPath id='clipper' clipPathUnits='objectBoundingBox'>
<path d='M0 0.1, 1 0, 0.85 1, 0.15 0.95' />
</clipPath>
</defs>
</svg>
<div class='svg-clip'>SVG Clip path</div>
Note: Though this shape can be achieved using CSS, it is better not to use CSS for such complex shapes.

As with many CSS properties relating to margins, padding and borders, there are four individual properties - one for each corner of a box element - and one shorthand property. Each of the corner attributes will accept either one or two values. The border-radius property will accept up to two values in WebKit browsers and up to eight now in Firefox 3.5.
-moz-border-radius: 36px 50px 50px 36px / 12px 30px 30px 12px
border-radius: 36px 50px 50px 36px / 12px 30px 30px 12px
Demo

Have a look here for explanation see here. Basically you will need a rectangle and four triangles or a parallelogram and two rectangles. Depends what you want to achieve.

#trapezium {
height: 0;
width: 80px;
border-bottom: 80px solid blue;
border-left: 40px solid transparent;
border-right: 40px solid transparent;
}
use this i thing usefull for you.

How to add an edge highlight to a CSS shape?

Hi I am trying to create a highlight on a CSS shape as shown below.
There will also be content inside of the hexagon including image and text,
The highlight I am referring to is the part in the top left.
the code I currently have for creating the hexagon is:
HTML
<div class="hexagon-big"></div>
CSS
.hexagon-big {
position: relative;
width: 200px;
height: 115.47px;
background-color: #343434;
}
.hexagon-big:before,
.hexagon-big:after {
content: "";
position: absolute;
width: 0;
border-left: 100px solid transparent;
border-right: 100px solid transparent;
}
.hexagon-big:before {
bottom: 100%;
border-bottom: 57.74px solid #343434;
}
.hexagon-big:after {
top: 100%;
width: 0;
border-top: 57.74px solid #343434;
}
There is other code for the content but i left it out because I don't think it is necessary
Do the hexagon shape differently and you can rely on gradient to create that highlight effect:
.hex {
width: 200px;
display: inline-flex;
margin:0 5px;
background:
conic-gradient(at top,#000 230deg, #0000 0),
linear-gradient(to bottom left,#fff , #000 60%);
clip-path: polygon(0% 25%,0% 75%,50% 100%,100% 75%,100% 25%,50% 0%);
}
.hex::before {
content: "";
padding-top: 115%; /* 100%/cos(30) */
}
<div class="hex"></div>
The solution in this answer is heavily based on the previous answer. To use clip-path and stacked gradients is by far the smartest thing to do here, but I still wanted to post this in order to show, how this solution could be improved and adjusted for your use case (text box, coloring, variables for maintenance, etc.).
.hexagon-big {
/* define box and text space */
width: 200px;
height: 230px;
padding: 10.8% 5px; /* adjust text box padding here; mind that top/bottom tip are part of the box */
box-sizing: border-box; /* width/height should include padding */
/* text formatting (optional) */
color: white;
text-align: center;
/* hex shape */
--hex-col: hsl(0deg 0% 20%); /* just your #343434 as a HSL color */
--hex-shadow: hsl(0deg 0% 50%); /* increased lightness by 15% to define highlight root color; 100% would be fully white */
background:
conic-gradient(at top, var(--hex-col) 232deg, transparent 0), /* change the angle of the shadow at "232deg": increase → narrower, decrease → wider */
linear-gradient(to bottom left, var(--hex-shadow), var(--hex-col) 55%);
clip-path: polygon(0% 25%,0% 75%,50% 100%,100% 75%,100% 25%,50% 0%);
}
<div class="hexagon-big">
Lorem ipsum dolor sit amet...
</div>
It should also be mentioned that your current way of using border is well better supported by older browsers than clip-path and conic-gradient (same with var()).
If this should be a problem, you might have to add another HTML tag and work out a way with transform: matrix(...) and box-shadow: inset ... (for example).

Add more than one gradient in border-image?

For background-image you can add as many radial-gradient and/or linear-gradient you want. But for border-image it seems like you can only add one. If find it quite strange, because the principle of how to display gradients should be the same for border and background, right?
Is there a way to add more than one gradient in border-image? I'm only interested in a pure CSS solution.
This doesn't work, because it contains more than 1 gradient:
div {
height: 30px;
width: 40px;
border: 50px solid black;
border-image:
radial-gradient(circle at 20px 30px, green 20px, rgba(0,0,255, .5) 20px),
radial-gradient(30deg, blue 22px, red 22px);
}
https://jsfiddle.net/thadeuszlay/p6r2p78g/
This works, but contains only one gradient:
div {
height: 30px;
width: 40px;
border: 50px solid black;
border-image: radial-gradient(circle at 20px 30px, green 20px, rgba(0, 0, 255, .5) 20px);
}
https://jsfiddle.net/thadeuszlay/p6r2p78g/1/
No, you can't set more than one image to the border-image shorthand or the border-image-source longhand property.
As per spec for border-image-source, we can see that only one image layer is specified as value.
Name: border-image-source
Value: none | <image>
whereas for background-image, we can see that multiple layers are specified.
Name: background-image
Value: <bg-image> [ , <bg-image> ]*
Below is an extract from the spec which introduces layering of background images: (emphasis mine)
The background of a box can have multiple layers in CSS3. The number of layers is determined by the number of comma-separated values in the ‘background-image’ property.
Just stubled upon this question when I was looking for the same thing.
But for other people, trying this:
You could just add a pseudo-element, and give that one a border too.
Guessing you would use transparent, because otherwise multiple gradients wouldn't be visible at all.
I've got the following:
h1{
--border-width: 5px;
border-width: var(--border-width);
border-style: solid;
border-image: linear-gradient(135deg, #ff0000, transparent 20%);
border-image-slice: 1;
font-size: 5rem;
position: relative;
}
h1::after{
position: absolute;
inset: calc(var(--border-width) * -1);
content: '';
background: transparent;
border-width: var(--border-width);
border-style: solid;
border-image: linear-gradient(135deg, transparent 80%, #ff0000 100%);
border-image-slice: 1;
}
I set the inset of the pseudo element to negative the border-width to make sure it aligns with the parents border.

CSS, is it possible to achieve this without an image?

I am making a website and on most websites it has a big image with massive text in it which says Welcome or something I have replicated the same thing but I was wondering is the image in the photo behind the OptimisePCs possible to achieve with plain CSS so no image, this is for performance reasons because people have to download the image to see it which takes time.
SVG
Here is an svg solution.
By setting the width to 100% on the svg element is scales with the page in the horizontal/x direction.
In other words this background is responsive.
Added the menu for fun.
body {
margin: 0;
}
.content {
width: 100%;
}
/* SVG background */
.svg-background {
width: 100%;
height: 100%;
}
.svg-background polygon:nth-child(1) {
fill: #005A50;
stroke: #005A50;
stroke-width: 0.1;
}
.svg-background polygon:nth-child(2) {
fill: #007367;
}
.svg-background polygon:nth-child(3) {
fill: #1C9F91;
stroke: #1C9F91;
stroke-width: 0.1;
}
.svg-background polygon:nth-child(4) {
fill: #3DAEA2;
}
/* NAVBAR Many for making it look better :D*/
.navigation {
background-color: #222;
}
.menu-bar {
display: block;
list-style: none;
margin: 0;
padding: 0;
height: 50px;
}
.menu-bar li {
display: inline-block;
color: white;
font-size: 20px;
//dding: 15px;
padding-right: 15px;
padding-left: 15px;
line-height: 2em;
height: 100%;
}
.menu-bar li:hover {
background-color: #72B1D7;
}
<nav class="navigation">
<ul class="menu-bar">
<li>OptimisePCs</li>
<li>Home</li>
<li>About</li>
<li>Services</li>
</ul>
</nav>
<div class="content">
<svg class="svg-background" viewBox="0 0 100 100">
<polygon points="0,0 10,0 0,20" />
<polygon points="10,0 0,20 0,100 50,100" />
<polygon points="10,0 50,100 70,100 80,0" />
<polygon points="80,0 70,100 100,100 100,0" />
</svg>
</div>
It seems like what you want is a background.
You can achieve this with multiple backgrounds and CSS linear-gradient values at various angles. You can use color stops which go from solid to transparent at the same spot to get the hard edges.
Here's an example:
header{
width: 100%;
height: 200px;
background: linear-gradient(60deg, #227766 25%, rgba(0,0,0,0) 25%),
linear-gradient(350deg, #40D2B3 20%, rgba(0,0,0,0) 20%),
linear-gradient(125deg, rgba(0,0,0,0) 70%, #39C1A5 70%),
linear-gradient(125deg, #2D9D87 45%, rgba(0,0,0,0) 45%),
linear-gradient(125deg, #35BEA2 70%, rgba(0,0,0,0) 70%);
}
<header></header>
As an added bonus, this is responsive out of the box. It will scale with the size of the container.
Additionally, you should set a solid background-color which will be the fallback for older browsers which lack support for gradients.
In this case using a svg might be more space efficient (and also scales to any resolution)
To use it in "pure CSS", you can inline the svg:
.selector { background: url('data:image/svg+xml;base64, ... svg code goes here ...'); }
Personally I use SCSS and the compass framework to make this easy:
.selector { background: inline-image("path/to/file.svg"); }
The drawback is that you have to take care not to inline it multiple times (or you replicate the code), if you need to do that, combine the respective classes instead:
.selector1, .selector2 { background: url('data:image/svg+xml;base64, ... svg code goes here ...'); }
image to css
using this site you can easily change image to css + !!
<style>
.pixels{
border-radius: 0;
display: inline-block;
width: 1px;
height: 1px;
box-shadow: bla~~
}
</style>
<div class="pixels"></div>

How to make a transparent border using CSS?

I'm trying to do something like this for a client who has a blog.
She wanted a semi transparent border. I know that's possible with making it just a background. But I can't seem to find the logic/code behind this kind of css technique for banners. Does anybody know how to do this? It would be a lot of help because that's the look my client's wanting to achieve for his blog....
Well if you want fully transparent than you can use
border: 5px solid transparent;
If you mean opaque/transparent, than you can use
border: 5px solid rgba(255, 255, 255, .5);
Here, a means alpha, which you can scale, 0-1.
Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.
For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.
Demo
Demo 2 (With a background image for nested div)
Demo 3 (With an img tag instead of a background-image)
body {
background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);
}
div.wrap {
border: 5px solid #fff; /* Fall back, not used in fiddle */
border: 5px solid rgba(255, 255, 255, .5);
height: 400px;
width: 400px;
margin: 50px;
border-radius: 50%;
}
div.inner {
background: #fff; /* Fall back, not used in fiddle */
background: rgba(255, 255, 255, .5);
height: 380px;
width: 380px;
border-radius: 50%;
margin: auto; /* Horizontal Center */
margin-top: 10px; /* Vertical Center ... Yea I know, that's
manually calculated*/
}
Note (For Demo 3): Image will be scaled according to the height and
width provided so make sure it doesn't break the scaling ratio.
You can also use border-style: double with background-clip: padding-box, without the use of any extra (pseudo-)elements. It's probably the most compact solution, but not as flexible as the others.
For example:
<div class="circle">Some text goes here...</div>
.circle{
width: 100px;
height: 100px;
padding: 50px;
border-radius: 200px;
border: double 15px rgba(255,255,255,0.7);
background: rgba(255,255,255,0.7);
background-clip: padding-box;
}
If you look closely you can see that the edge between the border and the background is not perfect. This seems to be an issue in current browsers. But it's not that noticeable when the border is small.
Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:
LIVE DEMO
<div class="circle"></div>
CSS:
.circle, .circle:before{
position:absolute;
border-radius:150px;
}
.circle{
width:200px;
height:200px;
z-index:0;
margin:11%;
padding:40px;
background: hsla(0, 100%, 100%, 0.6);
}
.circle:before{
content:'';
display:block;
z-index:-1;
width:200px;
height:200px;
padding:44px;
border: 6px solid hsla(0, 100%, 100%, 0.6);
/* 4px more padding + 6px border = 10 so... */
top:-10px;
left:-10px;
}
The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.
use rgba (rgb with alpha transparency):
border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity
The alpha transparency variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)

Transparent CSS background color

This question already has answers here:
How do I reduce the opacity of an element's background using CSS?
(29 answers)
Closed yesterday.
I want to make the list menu's background disappear by using opacity, without affecting the font. Is it possible with CSS3?
now you can use rgba in CSS properties like this:
.class {
background: rgba(0,0,0,0.5);
}
0.5 is the transparency, change the values according to your design.
Live demo http://jsfiddle.net/EeAaB/
more info http://css-tricks.com/rgba-browser-support/
Keep these three options in mind (you want #3):
1) Whole element is transparent:
visibility: hidden;
2) Whole element is somewhat transparent:
opacity: 0.0 - 1.0;
3) Just the background of the element is transparent:
background-color: transparent;
To achieve it, you have to modify the background-color of the element.
Ways to create a (semi-) transparent color:
The CSS color name transparent creates a completely transparent color.
Usage:
.transparent{
background-color: transparent;
}
Using rgba or hsla color functions, that allow you to add the alpha channel (opacity) to the rgb and hsl functions. Their alpha values range from 0 - 1.
Usage:
.semi-transparent-yellow{
background-color: rgba(255, 255, 0, 0.5);
}
.transparent{
background-color: hsla(0, 0%, 0%, 0);
}
As of the CSS Color Module Level 4, rgb and hsl works the same way as rgba and hsla does, accepting an optional alpha value. So now you can do this:
.semi-transparent-yellow{
background-color: rgb(255, 255, 0, 0.5);
}
.transparent{
background-color: hsl(0, 0%, 0%, 0);
}
The same update to the standard (Color Module Level 4) also brought in support for space-separated values:
.semi-transparent-yellow{
background-color: rgba(255 255 0 / 0.5);
}
.transparent{
background-color: hsla(0 0% 0% / 0);
}
I'm not sure why would these two be any better than the old syntax, so consider using the a-suffixed, comma-separated variants for greater support.
Besides the already mentioned solutions, you can also use the HEX format with alpha value (#RRGGBBAA or #RGBA notation).
That's contained by the same CSS Color Module Level 4, so it has worse support than the first two solutions, but it's already implemented in larger browsers (sorry, no IE).
This differs from the other solutions, as this treats the alpha channel (opacity) as a hexadecimal value as well, making it range from 0 - 255 (FF).
Usage:
.semi-transparent-yellow{
background-color: #FFFF0080;
}
.transparent{
background-color: #0000;
}
You can try them out as well:
transparent:

yes, thats possible. just use the rgba-syntax for your background-color.
.menue {
background-color: rgba(255, 0, 0, 0.5); //semi-transparent red
}
Here is an example class using CSS named colors:
.semi-transparent {
background: yellow;
opacity: 0.25;
}
This adds a background that is 25% opaque (colored) and 75% transparent.
CAVEAT
Unfortunately, opacity will affect then entire element it's attached to.
So if you have text in that element, it will set the text to 25% opacity too. :-(
The way to get past this is to use the rgba or hsla methods to indicate transparency* as part of your desired background "color". This allows you to specify the background transparency*, independent from the transparency of the other items in your element.
Technically we're setting the opacity, though we often like to speak/think in terms of transparency. Obviously they are related, inverses of each other, so setting one decides the other.
The number specified is the opacity %. 1 is 100% opaque, 0% transparent & vice versa).
Here are 3 ways to set a blue background at 75% opacity (25% transparent), without affecting other elements:
background: rgba(0%, 0%, 100%, 0.75)
background: rgba(0, 0, 255, 0.75)
background: hsla(240, 100%, 50%, 0.75)
In this case background-color:rgba(0,0,0,0.5); is the best way.
For example: background-color:rgba(0,0,0,opacity option);
Try this:
opacity:0;
For IE8 and earlier
filter:Alpha(opacity=0);
Opacity Demo from W3Schools
Yes you can just plain text as
.someDive{
background:transparent
}
For your case, we can use rgba():
First, we manipulate the background-color, and use rgba.
.selector {
background-color: rgba(0, 0, 0, 0.3);
}
Now what this does is, it basically adds an opacity to your element, along with the black background color. This is how it'd look when you run it.
body {background-color: #0008f3;}
.container {
height: 100px;
width: 100px;
background-color: rgba(255,255,255,0.5);
}
<body>
<div class="container"></div>
</body>
full transparent -> .youClass{background: rgba(0,0,0,0.001);}
